When opening the lastpass extension icon a blank transparent frame is generated where the log on screen would usually be.

Esc and re clicking brings up the expected window.

Also there is a binary component for the Lastpass extension which installs a binary version of the extension and is required to store files within Lastpass. This has a separate installer that is downloadable, however it doesn’t appear to install on Brave but does on my Chrome browser.

I experience those same issues. In addition, when LastPass vault is open, everything in it works perfectly - except accessing Chase Bank. I’ve also noted this on a longer thread about accessing Chase Bank, but it should also be noted here. When using LastPass on Safari, Firefox, Chrome, or Opera I have not trouble accessing our Chase account. Because that’s true, I can only assume a fix is needed on Brave. An issue that will likely require Brave and Chase tech/programming teams to work out together.
